Three-degree of freedom parallel serial upper limb rehabilitation robot

Abstract

The invention discloses a three-degree of freedom parallel serial upper limb rehabilitation robot and belongs to the technical field of medical rehabilitation devices. The three-degree of freedom parallel serial upper limb rehabilitation robot is formed by a parallel mechanism and a serial rotating pair in an overlapped mode. A moving platform (7) and a static platform (4) are connected through a branched chain AB (3), a branched chain CD (5) and a branched chain EF (6) to form the parallel mechanism. The three degree of freedom parallel serial upper limb rehabilitation robot achieves gesture rotation around an X axis, a Y axis and a Z axis, different drive can be set according to pathogenetic conditions of patients, recovery training of a wrist joint or a forearm can be selectively achieved, and then different recovery training effects can be achieved. The three-degree of freedom parallel serial upper limb rehabilitation robot solves the problems that an existing limb rehabilitation robot is single in form, large in occupied space, large in chain length and large in weight, and large drive force is needed.

AI Technical Summary

Benefits of technology

This patented technology allows for robots that move freely within their environment without being limited by fixed infrastructure or physical constraints like positioning them accurately on specific directions. These machines have several technical benefits such as they take up less room than traditional systems while still providing precise movements about all six degrees of freedom (X-,Y-,Z). They also provide excellent performance at lower costs compared with current methods due to its simplicity design and strong mechanical properties.

Problems solved by technology

The technical problem addressed in this patented text relating to stroke treatment involves developing robotic devices capable of providing various movements or motions while being able to accurately measure their performance over time during medical procedures such as surgery. Current methods involve complex mechanical systems like serial machines requiring human effort and subjective assessments.
